So, here you have muslims entering a Jewish synagogue but in Jerusalem, no one but Muslims can enter the grounds of their mosque on the Temple mount. I’d say they were casing out the synagogue to cause a terrorist act or to instigate confrontation with Jews.

Forget Jerusalem, if non-Muslims took the Bible or Torah into a mosque – it would be national news with CAIR calling for an investigation by the FBI – whom they teach their fellow Muslims not to talk to.
